Forecast models from the National Weather Service and private providers converge on a high near 90°F in Central Park for August 7, driven by southerly flow off a Bermuda high that advects warm, humid air northward while a weak trough allows afternoon instability and scattered storms. This setup supports the market’s emphasis on the 90-91°F bin (42.5% implied probability) over cooler or hotter alternatives, as daytime mixing and limited cloud cover favor peak readings in the low 90s rather than sustained mid-90s heat. Heat-index values near 100°F reflect elevated dew points, yet any earlier or heavier convection could trim the actual maximum by a degree or two. Updated model runs and the evening NWS forecast discussion remain the key near-term catalysts for shifts in trader positioning ahead of the daily observation.
